Serial No. 442,055.

The present. invention relates to improvements in boring machines, andhas particular milling machine.

Various objects of the invention reside in the PI'OVlSlOII of a novelhorizontal boring,

drilling and milling machine inwhich the work saddle, the work table,the headstock and the end block may be driven independently of eachother in direction and speed, and in which the direction control memberfor each unit is movable by the operator in the same direction as thatto be initiated for the unit, thereby increasing the usefulness andadaptability of the machine and simplifying the manual control thereof.

Another object resides in the provision of a machine of the foregoingcharacter cornprising a. headstock which includes as an integral unitall of the variable speed drives gpr rotating and feeding the spindle orspin Other objects reside in" the provision of a new and improvedheadstock having a main spindle. an auxiliary spindle from which therotative drive for the main spindle is taken, and means includinginterlocks for selectively feeding spindles axially.

Various other objects reside in the provision of novel clamping devices,clutches, clutch interlocks, clutch actuating means, coordinated drivegearing, coolant distributing means. etc. a

Ancillary objects and advantages will become apparent as the descriptionproceeds.
